Terre Products, 18 Pack, Robotic Lawn Mower Replacement Blades, Compatible with Husqvarna Automower, Gardena Sileno, McCulloch

What It Is

This 18-pack of replacement blades is designed for robotic mowers, specifically Husqvarna Automower, Gardena Sileno, and McCulloch models. It provides a cost-effective way to maintain sharp cutting performance on small to medium lawns.

Fitment & Compatibility

Before buying, verify your mower’s model number (e.g., Husqvarna 305, 315, 430X; Gardena Sileno City, Life, Minimo; McCulloch ROB S, R1000). These blades are aftermarket, not OEM, so they may differ slightly in thickness or edge geometry. Measure your existing blades: they should be approximately 3.5 inches long and 0.75 inches wide, with a center hole diameter of 6mm. They fit decks up to 22 inches (most robotic mowers). Avoid using on larger commercial models or older Husqvarna Automowers (pre-2015) without cross-checking dimensions.

Key Things to Know

• Quality vs. OEM: These blades are hardened steel but may wear faster than OEM Husqvarna parts. Expect 4–6 weeks of cutting before needing replacement, depending on grass conditions.
• Installation Difficulty: Easy—no tools required for most models (just snap off the old blade and press on the new one). Ensure blades are oriented correctly: the cutting edge should face the direction of rotation.
• Common Gotcha: The 18-pack includes six sets of three blades. Each mower uses three blades, so this pack covers six full changes. Don’t mix with other brands or sizes—binding or poor cut quality can result.
• Noise/Vibration: Aftermarket blades may produce slightly more vibration than OEM. If your mower has a sensitive suspension, this could affect performance on uneven terrain.

Should You Buy It

If you have a compatible Husqvarna, Gardena, or McCulloch robotic mower and want a budget-friendly, bulk replacement option for regular blade swaps, this pack is a solid choice. It’s ideal for owners who change blades every 4–6 weeks and don’t mind slight trade-offs in longevity versus OEM parts. For heavy-duty use or large lawns, stick with OEM blades for consistent performance.
